Big Wave is a large-scale commercial project which has been approved, though not yet built in Moss Beach. It is located in a high-risk tsunami zone and is estimated to generate 1500 daily car trips* in and out of the development, through narrow neighborhood roads. Here are other key points:


• 8 total buildings, including 5 large office buildings

• The office buildings alone are equivalent to the size of approximately 1.5 Walmarts

• Wellness Center and housing for 50 developmentally disabled adults and 20 caretakers

• Large boat storage facility

• Parking lots for approx 500 cars

Big Wave & Beer Brewery

In June 2017, the San Mateo County Board of Supervisors approved an amendment to the Big Wave agreement. This paves the path for a commercial beer brewing facility to be built at Big Wave, raising concerns about the cumulative impacts on traffic and sewage.

High-Risk Tsunami Zone

Scientists consider Half Moon Bay one of the top five most vulnerable points in CA for a tsunami.*


A devastating earthquake off the south coast of Alaska would send a shockwave of water toward the San Francisco Bay Area that drives the ocean up about 30 feet on San Mateo County shores. Pillar Point Harbor, Princeton and the southern reaches of the airport would be under water.
